The present invention relates to a band-shaped member connecting body and a band-shaped member connecting jig for connecting the ends of two metal band-shaped members.

2. Description of the Related Art In a working machine that assembles a predetermined product, a long belt-like member is sometimes used as a material for the predetermined product or as a means for transporting parts. Such a band-like member is wound around a reel, and is continuously fed out from the reel to a working machine by a feeding mechanism.

As such a band-shaped member, there is one such as that disclosed in Patent Document 1, for example. The belt-shaped member of Patent Document 1 is made of a thin metal plate, and a plurality of terminals that are crimped to the ends of electric wires are connected in parallel at equal intervals on one side extending in the longitudinal direction. This band-shaped member is wound onto a reel for a predetermined length by a winding machine. In addition, this belt-shaped member has a plurality of feed holes lined up at equal intervals in the longitudinal direction that can be engaged with the feed pawl of the feed mechanism, and by moving the feed pawl toward the working machine, the reel can be removed from the reel. The strip members are pulled out one after another, and the terminals are continuously delivered to the working machine. Since the terminals connected to the strip member can be continuously supplied to the working machine in this way, the assembly efficiency of the product is high.

JP 2016-46077 (Page 6, Figure 2)

The band-shaped member as in Patent Document 1 is made of a thin metal plate that can be bent and deformed, so it can be easily wound around a reel. When winding the belt-shaped member onto a reel, stress is applied to the belt-shaped member in a tensile direction or a torsional direction, and the belt-shaped member may break during winding. In such cases, the conventional method was to connect the spout holes of the two broken belt-shaped members with a connecting member such as wire, but in addition to being difficult to align the belt-shaped members, the connection strength was insufficient. There is a risk that the strip members may be misaligned with each other, and there is a risk that problems may occur during assembly work using a work machine or during delivery work using a delivery mechanism.

The present invention has been made with attention to such problems, and an object of the present invention is to provide a band-shaped member connecting body and a band-shaped member connecting jig that can restrict the positional shift of a pair of band-shaped members.

In order to solve the above problems, the strip member connecting body of the present invention has the following features:
A band-shaped member connection body in which opposing ends of a pair of metal band-shaped members are connected to each other by a fitting part that is irremovably fitted in the longitudinal direction and the width direction ,
Opposing ends of the pair of band-like members have opposing surfaces that are opposite in the width direction,
A plurality of the fitting portions are provided along the longitudinal direction between the facing surfaces facing each other in the width direction,
The fitting surface of the fitting portion is characterized in that uneven portions are formed facing each other in the thickness direction.
According to this feature, the relative movement of the pair of band-shaped members in the longitudinal direction and the width direction is regulated by the fitting of the fitting parts, and the fitting of the pair of band-shaped members in the respective uneven parts formed on the opposing engagement surfaces Since the relative movement of the members in the thickness direction is restricted, it is possible to connect the pair of band-like members with mutual positional displacement being restricted.

Each engagement surface of the fitting portion is characterized in that it is formed by shearing.
According to this feature, each engagement surface is formed by shearing each metal band member, so the characteristics of each opposing engagement surface are similar, and the fit between the fitted engagement surfaces is good. It is.

Each engagement surface of the fitting portion is characterized by being formed with the same cutting blade.
According to this feature, since the opposing engaging surfaces are formed with the same cutting blade, the engaging surfaces can be formed into corresponding shapes, and the engagement precision between the engaging surfaces is high.

Each of the engagement surfaces of the fitting portion has a tapered surface that tapers toward one of the thickness directions, and the engagement surfaces are engaged flush with each other.
According to this feature, since the engaging surfaces are brought into pressure contact with each other by the tapered surfaces, a fitting force can be applied to the fitting portions, and the fitting portions can be firmly fitted and connected to each other.

The pair of band-shaped members are characterized in that they are made of a metal material mainly containing copper.
According to this feature, since the pair of band-like members is made of a metal material mainly containing copper that is easily deformed flexibly, external force is applied to the connected pair of band-like members in the direction of twisting or bending. When the force is applied, the band-like member deforms and absorbs the external force, making it difficult for the fitted portion to come off.

The strip member connecting jig of the present invention includes:
A jig for connecting a pair of metal strip members,
An end of the pair of band-shaped members having opposing surfaces facing each other in the width direction, and a plurality of fitting portions provided along the longitudinal direction between the opposing surfaces and fitting irremovably in the longitudinal direction and the width direction. cutting means for forming respective portions;
It is characterized by comprising a pressing means that presses the end portions in the thickness direction to fit them together.
According to this feature, the uneven portions are formed facing each other in the thickness direction of the engaging surfaces facing each other at the ends due to the shearing force generated when cutting the pair of band-like members by the cutting means, and the end portions are formed by the pinching means. When they are fitted together, relative movement in the longitudinal and width directions of the pair of band-shaped members is restricted by the fitting of their ends, and the fitting of the uneven portions of each engagement surface restricts the relative movement of the pair of band-shaped members. Since relative movement in the thickness direction is restricted, it is possible to connect the pair of belt-like members while restricting mutual positional displacement.

It is characterized in that the cutting means and the pressing means are arranged side by side in the width direction of the pair of band-shaped members .
According to this feature, after the end portions are formed on the strip-shaped member by the cutting means, the strip-shaped member can be continuously transferred to the clamping means in a short time.

a mounting table on which the strip-shaped member can be placed, and the mounting table includes cutting movement restriction means that abuts in the longitudinal direction of the strip-shaped member to restrict movement of the strip-shaped member with respect to the cutting means; The present invention is characterized in that a clamping movement restricting means is provided which abuts in the longitudinal direction of the pair of band-shaped members and restricts movement of the end portions.
According to this feature, each strip-shaped member can be positioned with respect to the cutting means by the movement restriction for cutting, so a pair of continuous strip-shaped members in a fixed pattern can be cut by the cutting means at corresponding positions, and the movement restriction for clamping can be cut by the cutting means. The pair of belt-shaped members can be connected by the pinching means by aligning the respective ends so that the pair of belt-shaped members are continuous in a fixed pattern.

The cutting movement regulating means and the pinching movement regulating means are pins inserted into a plurality of feed holes provided along the longitudinal direction of the strip member, and the pins sandwich the cutting means and the pinching means. It is characterized by the fact that they are placed on both sides.
According to this feature, a plurality of feed holes provided along the longitudinal direction of the strip member and a pin inserted through the feed hole are used to position the strip member relative to the cutting means and to position each end of the pair of strip members. The structure of the band member can be simplified. In addition, since the pins are arranged on both sides of the cutting means and the pinching means, it is possible to cut accurately while suppressing distortion and misalignment of the strip member during cutting, and when pinching, the ends of the pair of strip members can be cut. It is possible to suppress misalignment between the two and securely fit them together.

The cutting blade of the cutting means and the pressing body of the pinching means are characterized in that they are operated by the same moving means.
According to this feature, since the cutting blade and the pressing body can be moved in the vertical direction with one moving means, the structure of the jig can be simplified.

The pressing body is characterized in that it is movably attached to the rear of the cutting means.
According to this feature, when the end portion of the band-shaped member is formed by the cutting means, the pressing body can be retracted to a rear position where it does not get in the way, making it easy to perform the cutting operation.

Further, the left side of the drawings in FIGS. 7 and 8 will be referred to as the front side (front side) of the strip-shaped member connecting jig, and the left and right directions as viewed from the front will be described as the left and right sides of the strip-shaped member connecting jig.

The strip member connecting body 1 shown in FIG. 4 is used for a working machine that assembles a predetermined product, and in this embodiment, a terminal 2a (see FIG. 2) is crimped to the end of an electric wire (not shown). The case where the terminal crimping machine 100 shown in FIG. 1 is used will be described as an example. Note that the strip member connecting jig 4 shown in FIGS. 7 and 8 is a jig for constructing the strip member connecting body 1.

As shown in FIG. 1, the terminal crimping machine 100 includes a reel R around which a strip-shaped continuous terminal 2 is wound, and a crimping machine that crimps a terminal 2a (see FIG. 2) of the continuous terminal 2 to the end of an electric wire (not shown). It includes a device 101 and a feeding mechanism 102 that pulls out the continuous terminal 2 from the reel R and feeds it to the crimping device 101.

As shown in FIG. 2, the continuous terminal 2 includes a long strip member 3 extending in the left-right direction, and a plurality of terminals 2a arranged at equal intervals along the left-right direction on the front long side 3a of the strip member 3. It is composed of and.

The strip member 3 of this embodiment is a metal material mainly containing copper, and has a thickness of about 0.1 mm to 0.3 mm. The material of the strip member 3 may be freely changed to other metals or alloys, but is preferably a flexible metal such as aluminum or copper. Further, the width, length, thickness, etc. of the band-shaped member 3 may also be changed freely.

In addition, the belt-shaped member 3 has a rectangular hole 3A as a feed hole penetrating in a substantially rectangular shape in a plan view, and a circular hole 3B as a feed hole penetrating in a substantially circular shape in a plan view, which are alternately and equally spaced along the left and right direction. are provided at intervals. The plurality of rectangular holes 3A are adapted to engage with a driving means (not shown) of the feeding mechanism 102, and the belt-shaped member 3 is moved toward the crimping device 101 by driving of the driving means. Further, the plurality of circular holes 3B are engaged with a driving means (not shown) of the crimping device 101, and are moved toward a cutter (not shown) that cuts the terminal 2a from the strip member 3 by driving the driving means. It is supposed to be done.

In such a continuous terminal 2, the longitudinal width of the region of the strip member 3 where the rectangular hole 3A and the circular hole 3B are provided is small. Therefore, for example, during the work of winding the continuous terminal 2 around the reel R or during the feeding operation by the feeding mechanism 102, stress acts on the strip member 3 in the tensile direction or torsional direction, and the virtual line passing through the rectangular hole 3A is The strip member 3 may break at the position α or at the position of the imaginary line β passing through the circular hole 3B.

In the first embodiment, when the strip member 3 is broken as described above, the opposing ends of the strip member 3 and the strip member 3' broken from the strip member 3 are By forming the cut ends 31, 31' and fitting the respective fitting parts 35a, 35b, 35c of the cut ends 31, 31', connection can be made without using wires, welding, etc. There is. In other words, it is possible to easily construct the strip member connection body 1 in which the strip member 3 and the strip member 3' are directly connected.

Next, a procedure for configuring the strip-shaped member connector 1 will be schematically explained. Here, we will take as an example the case where the strip member 3 breaks along the imaginary line α, and connect the strip member 3 and the strip member 3' directly using a strip member connecting jig 4, which will be described later. The procedure for configuring the body 1 will be explained.

It is composed of a second side portion 33 extending to the long side 3a, and a third side portion 34 extending from the left end of the first side portion 32 to the long side 3b of the strip member 3. This cut end portion 31 is formed by a cutting means 41 which will be described later. Note that the portion of the strip member 3 between the cut end 31 and the imaginary line α is unnecessary waste strip material 300.

The first side portion 32 extends across the two rectangular holes 3A and the three circular holes 3B, and a fitting recess 32a recessed toward the front is formed between each of the adjacent rectangular holes 3A and the circular holes 3B. ing.

In this fitting recess 32a, the left-right width L1 of the open end opening toward the rear is smaller than the left-right width L2 of the front end (see FIG. 4 (L1<L2)).

The second side portion 33 is formed with a fitting convex portion 33a that protrudes toward the right side of the strip member 3. The fitting convex portion 33a of the second side portion 33 is formed so that its left end portion is narrower in the front-rear direction than its right end portion in plan view.

Further, the third side portion 34 is formed with a fitting recess 34a that is recessed toward the left side of the strip member 3. The fitting recess 34a of the third side 34 is formed so that the right end is narrower in the front-rear direction than the left end when viewed from above.

Next, as shown in FIG. 3(b), a cut end portion 31' is formed at an arbitrary position shifted to the right of the imaginary line α in the strip member 3' that is broken from the strip member 3. This cut end 31' has a first side 32' that extends in the longitudinal direction so as to pass through the center of the rectangular hole 3A and the circular hole 3B and is divided in the width direction, and a band-like shape from the right end of the first side 32'. It is composed of a second side 33' extending to the long side 3a of the member 3, and a third side 34' extending from the left end of the first side 32' to the long side 3b of the strip member 3. This cut end 31' is formed by the same cutting means 41 used when the cut end 31 was formed. Note that the portion of the strip member 3' between the cut end 31' and the imaginary line α is unnecessary waste strip material 300'.

The first side portion 32' extends across the two rectangular holes 3A and the three circular holes 3B, and has a fitting convex portion 32a' that protrudes forward between the adjacent rectangular holes 3A and the circular holes 3B. each formed.

In this fitting convex portion 32a', the lateral width L1' of the rear base end is smaller than the lateral width L2' of the front end (see FIG. 4 (L1'<L2')).

A fitting recess 33a' recessed toward the right side of the strip member 3 is formed in the second side portion 33'. The fitting recess 33a' of the second side 33' is formed so that its left end is narrower in the front-rear direction than its right end when viewed from above.

Furthermore, a fitting convex portion 34a' that protrudes toward the left side of the strip member 3 is formed on the third side portion 34'. The fitting convex portion 34a' of the third side portion 34' is formed so that the right end portion is narrower in the front-rear direction than the left end portion when viewed from above.

Since the cut ends 31, 31' are formed by the cutting means 41 of the same strip member connecting jig 4, which will be described later, as shown in FIG. 4, the cut ends 31, 31' are The same cutting line is formed, and by fitting the respective recesses and protrusions in the thickness direction, the belt-like member 3 and the belt-like member 3' are connected without shifting.

Specifically, each fitting recess 32a of the cut end 31 and each fitting convex part 32a' of the cut end 31' fit together, and the fitting convex part 33a of the cut end 31 and the fitting convex part 32a' of the cut end 31' fit together. The fitting recess 33a' of the cut end 31 and the fitting convex 34a' of the cut end 31 are fitted together. That is, each fitting recess 32a and each fitting protrusion 32a' constitute a fitting part 35a, the fitting protrusion 33a and fitting recess 33a' constitute a fitting part 35b, and the fitting concave part 34a and the fitting convex portion 34a' constitute a fitting portion 35c.

According to this, the relative movement of the band members 3, 3' in the left-right direction (longitudinal direction) is regulated by the fitting of the respective fitting parts 35a, and the band-shaped members 3, 3' are restricted by the fitting of the fitting parts 35b and 35c. Relative movement of the members 3, 3' in the front-rear direction (width direction) is restricted.

Further, the fitting recess 32a and the fitting protrusion 32a' are formed so that the left and right widths L1 and L1' on the front side are narrower than the left and right widths L2 and L2' on the rear side. Relative movement in the direction in which ' is spaced back and forth is also restricted.

Further, the fitting convex portion 33a and the fitting concave portion 33a' are formed so that the longitudinal width of the left end portion is narrower than the longitudinal width of the right end portion, and the fitting convex portion 34a and the fitting convex portion 34a '' means that the front-to-back width of the right end is narrower than the front-to-back width of the left end, so relative movement of the band-like members 3, 3' in the direction in which they are separated from each other in the left and right directions is also restricted.

Further, as shown in FIG. 5, on the opposing engagement surfaces 31a, 31a' of each fitting part 35a, recesses 31b, 31b' and protrusions 31c, 31c' are opposed to each other in the thickness direction, respectively. It is formed. In this way, since the engaging surfaces 31a, 31a' are pressed against each other with the concave portions 31b, 31b' and the convex portions 31c, 31c' facing each other and engaging with each other, the relative relationship in the thickness direction of the strip members 3, 3' is Movement is restricted. In FIG. 5, for convenience of explanation, the recesses 31b, 31b' and the convex parts 31c, 31c' are shown larger than they actually are.

Further, the engaging surfaces 31a, 31a' have tapered surface portions 36, 36' that taper upward, respectively, and the fitting force is applied to the fitting portions 35a, 35b, 35c by pressure contact of the tapered surface portions 36, 36'. The fitting parts 35a, 35b, and 35c are firmly fitted and connected.

In this embodiment, after forming the cut end portion 31 on one strip member 3, the cut end portion 31' is formed on the other strip member 3'. After forming the cut end 31', the cut end 31 may be formed on one of the strip members 3. Alternatively, the cut end portion 31 and the cut end portion 31' may be cut and formed using separate jigs.

Next, the structure of the strip-like member connecting jig 4 used to construct the strip-like member connecting body 1 will be explained using FIGS. 6 to 9. FIG.

As shown in FIG. 6, the strip member connecting jig 4 includes a mounting table 40 on which the strip members 3, 3' can be placed, a cutting means 41 for cutting the strip members 3, 3', and a cutting means 41 for cutting the strip members 3, 3'. , 3', and a moving means 43 that moves the cutting blade 41A of the cutting means 41 and the pressing body 42A of the pinching means 42 in the vertical direction.

Further, on the mounting surface 40a, two pins 6 as a clamping movement restricting means are provided in rows on both left and right sides of the clamping means 42, spaced apart in the left-right direction.

As shown in FIG. 7, the mounting table 40 is formed with a through hole 40A that penetrates in the vertical direction near the support 45, and a cutting blade 41A can be inserted into the through hole 40A. (See Figure 8).

Referring to FIG. 9, the through hole 40A has an edge surface 40b on its front side that has substantially the same shape as the cut end 31 in plan view and extends in the vertical direction. Hereinafter, a portion near the corner formed by the mounting surface 40a and the edge surface 40b will be referred to as an edge 40c (see FIG. 10(b)).

Next, the moving means 43 will be explained. As shown in FIG. 7, the moving means 43 includes an upper moving body 431 disposed above the mounting table 40, a lower moving body 432 disposed below the mounting table 40, and rotation with respect to the column 45. It is mainly composed of a rotating body 433 that is rotatably supported, and a link member 434 that is rotatably supported between the lower moving body 432 and the rotating body 433.

The upper moving body 431 is a rectangular metal plate member larger than the through hole 40A in plan view, and a biasing spring 435 is arranged between the rear end of the upper moving body 431 and the mounting surface 40a. has been done. Further, a cutting blade 41A inserted through the through hole 40A is connected to the lower part of the upper moving body 431.

The lower moving body 432 has a rectangular base portion 432a that is larger than the through hole 40A in plan view, and side plate portions 432b extending downward from both left and right ends of the base portion 432a. That is, the lower moving body 432 has a downward U-shape when viewed from the front. This lower moving body 432 is connected below the cutting blade 41A inserted into the through hole 40A.

The rotating body 433 is rotatably supported by a shaft 433a extending in the left-right direction with respect to the side plate portion 45a of the support column 45. Further, a lever 46 extending upward is connected to the rotating body 433 so as to be disposed on the front side of the mounting table 40 .

The link member 434 has an upper end rotatably supported by a side plate 432b of the lower movable body 432 by a shaft 434a extending in the left-right direction, and a lower end thereof is rotatably supported by a shaft 434b extending in the left-right direction. 433 so as to be rotatable.

Next, the cutting means 41 will be explained. Referring to FIG. 10(b), the cutting means 41 includes a cutting blade 41A and an edge 40c of the mounting table 40. The cutting blade 41A is made of metal and has a U-shape when viewed in side cross section. Hereinafter, the upper front surface of the cutting blade 41A will be referred to as a side surface 41a, the surface extending horizontally from the side surface 41a will be referred to as a tip surface 41b, and the surface facing below the tip surface 41b will be referred to as an opposing surface 41d.

Returning to FIG. 7, when the strip-shaped member connecting jig 4 is not operated, the tip surface 41b of the cutting blade 41A and the mounting surface 40a are separated in the vertical direction due to the urging force of the urging spring 435, and are opposed to each other. The surface 41d is arranged on the same plane as the mounting surface 40a (see FIG. 10(b)). Between the distal end surface 41b of the cutting blade 41A and the mounting surface 40a, the band-like members 3, 3' can be inserted from the front side.

Referring to FIG. 9, the side surface 41a of the cutting blade 41A has substantially the same shape as the cutting end 31' in plan view. The outer shape of the cutting blade 41A when viewed from above is slightly smaller than the outer shape of the through hole 40A when viewed from above, and a small clearance C (see FIG. 12(a)) is formed between the side surface 41a and the edge surface 40b. ), the cutting blade 41A and the through hole 40A move relative to each other vertically.

Next, the clamping means 42 will be explained. Returning to FIG. 7, the clamping means 42 is composed of a pressing body 42A and a mounting surface 40a.

The pressing body 42A is made of a metal plate member, and includes a first extending piece 421 extending in the horizontal direction and a second extending piece 422 extending downward from the front end of the first extending piece 421. , and has a substantially L-shape when viewed in side cross section.

This pressing body 42A is attached to the upper movable body 431 by a shaft supporting member 47 that extends in the vertical direction at the rear end of the first extending piece portion 421. Further, the pressing body 42A is horizontally rotatable around the shaft supporting member 47, and is at a pressing position where the second extending piece portion 422 is disposed on the front side of the cutting means 41 (FIG. 11(a) ) and a retracted position (the state shown in FIG. 10A) in which the second extending piece portion 422 is arranged on the rear side of the cutting means 41.

Further, the lower end surface of the second extending piece portion 422 is a flat surface 422a parallel to the mounting surface 40a, and the flat surface 422a is large enough to press the entire cut ends 31, 31' in the thickness direction. (See Figure 13). When the strip-shaped member connecting jig 4 is not operated, the mounting surface 40a and the flat surface 422a are vertically separated from each other by the biasing force of the biasing spring 435. The belt-like members 3, 3' can be inserted and arranged from the front side.

As shown in FIG. 8, when the lever 46 is operated downward from the state shown in FIG. 7, the rotating body 433 rotates downward, and the link member 434, the lower moving body 432, and the upper moving body 431 are pulled down. Since the holding member 437 attached to the upper moving body 431 via the spring 436 moves toward the mounting surface 40a, it cannot press the strip member 3 or the strip member 3' arranged on the mounting surface 40a. It is now possible to do so. Then, by compressing the spring 436 to its limit, the downward movement of the lower moving body 432 and the upper moving body 431 is restricted.

At this time, the tip surface 41b of the cutting blade 41A is arranged below the mounting surface 40a, and the flat surface 422a of the pressing body 42A is pressed against the mounting surface 40a. Note that when the lever 46 is released, the moving means 43 is urged upward by the urging spring 435, and the front end of the lower moving body 432 is locked to the lower surface of the mounting table 40. It is designed to return to the state of 4 when not operated.

Next, a procedure for constructing the strip-like member connection body 1 using the strip-like member connection jig 4 will be explained. Note that illustration of the terminals 2a connected to the strip members 3, 3' is omitted.

First, as shown in FIG. 10(a), the pressing body 42A is rotated and placed in the retracted position, and the band member 3 extending in the left-right direction is placed between the cutting blade 41A and the mounting surface 40a. At this time, as shown in FIG. 10(b), the strip member 3 is placed between the mounting surface 40a and the opposing surface 41d of the cutting blade 41A.

Further, as shown in FIG. 10(c), the strip member 3 is inserted through a rectangular hole 3A and a circular hole 3B corresponding to each pin 5, so that positioning of the strip member 3 with respect to the cutting means 41 is facilitated. be done.

Next, from the state shown in FIG. 10, the lever 46 is operated to move the cutting blade 41A downward to form the cutting end 31 at the end of the strip member 3 (see FIG. 3(a)). The strip member 3 on which the cut end portion 31 has been formed and the unnecessary waste strip material 300 generated when the cut end portion 31 is formed are once removed from each pin 5, and the cut end portion 31 is attached to the strip member 3′ in the same manner as in the above process. ' (see Figure 3(b)). A specific manner of forming the cut ends 31, 31' by the cutting means 41 will be described in detail later.

Next, as shown in FIGS. 11(a) and 11(b), the pressing body 42A is rotated and placed in the pressing position, and a band-shaped member is placed between the mounting surface 40a and the flat surface 422a of the pressing body 42A. Place 3, 3'. At this time, as shown in FIG. 11(c), the rectangular hole 3A and the circular hole 3B corresponding to each pin 6 are inserted through the strip members 3, 3', respectively, so that the cut ends 31, 31 ' are aligned to positions where they can fit into each other.

Next, from the state shown in FIG. 11, the lever 46 is operated to move the pressing body 42A downward, and the fitting parts 35a, 35b, By compressing and fitting 35c in the thickness direction, a strip member connecting body 1 to which the strip members 3 and 3' are connected is constructed (see FIG. 4). A specific manner in which the fitting portions 35a, 35b, 35c of the cut ends 31, 31' are fitted together by the pinching means 42 will be described in detail later.

Next, a mode in which the cut ends 31, 31' are formed by the cutting means 41 and a mode in which the fitting portion 35a is fitted together by the pinching means 42 will be specifically explained based on FIGS. 12 and 13. Note that FIGS. 12 and 13 are front sectional views showing a mode of forming an arbitrary fitting portion 35a.

As shown in FIG. 12(a), a clearance C is formed between the side surface 41a of the cutting blade 41A and the edge surface 40b of the mounting table 40. This clearance C is smaller than the thickness of the strip member 3.

When the cutting blade 41A is lowered to the state shown in FIG. 12(b), the portion 301 of the strip member 3 that vertically overlaps the mounting surface 40a of the mounting table 40 remains disposed on the mounting surface 40a, and A portion 302 of the member 3 that vertically overlaps the tip surface 41b of the cutting blade 41A is pushed down. That is, a shearing force is applied to the strip member 3 by the cutting blade 41A and the edge 40c of the mounting table 40.

At this time, the portion 301 on the edge 40c side has a curved sagging surface portion 301a and a vertically straight sheared portion extending along the side surface 41a of the cutting blade 41A by being pulled downward by the cutting blade 41A. A surface portion 301b is formed. The sagging surface portion 301a is formed at the upper portion of the portion 301 near the side surface 41a of the cutting blade 41A, and the sheared surface portion 301b is formed at the lower portion of the sagging surface portion 301a.

On the other hand, the portion 302 on the side of the cutting blade 41A is pulled upward by the edge 40c to form a curved sagging surface portion 302a and a vertically straight sheared surface portion 302b extending along the edge 40b. Ru. The sagging surface portion 302a is formed at a lower portion of the portion 302 near the edge surface 40b, and the sheared surface portion 302b is formed at the upper portion of the sagging surface portion 302a.

In addition, in the vicinity of the corner 41c of the cutting blade 41A and the corner 40d of the edge 40c in the strip member 3, cracks 310, 311 are generated toward the corners 41c, 40d due to the tensile force between the parts 301, 302. arise.

Furthermore, when the cutting blade 41A is lowered to the state shown in FIG. A broken surface portion 302c is formed above the sheared surface portion 302b of the portion 302. That is, the strip member 3 is separated into the strip member 3 on the mounting surface 40a side in which the fitting recess 32a is formed, and the unnecessary waste strip material 300 on the cutting blade 41A side.

These fractured surface portions 301c and 302c constitute tapered surface portions 36 and 36'. Since the fractured surfaces 301c and 302c are formed by the tensile force between the parts 301 and 302, a plurality of convex parts 31c and 31c' that are plastically deformed so as to protrude from the parts 301 and 302 on the opposite side are formed.

Further, a burr portion 301d is formed at the lower end edge of the fractured surface portion 301c of the band member 3, which extends downward due to the downward tensile force. Furthermore, a burr portion 302d is formed at the upper end of the broken surface portion 302c of the waste strip material 300 (ie, the portion 302) due to the upward pulling force.

As described above, after the cutting (shearing) of the strip member 3 is completed, the strip member 3' is sheared in the same procedure as the above process. As a result, the strip member 3' on the side of the cutting blade 41A in which the fitting convex portion 32a' is formed and the unnecessary waste strip material 300' on the side of the mounting surface 40a are separated. Note that the engagement surface 31a' of the strip member 3' has substantially the same shape as the waste strip material 300.

Next, a description will be given of a form in which the fitting recess 32a and the fitting protrusion 32a' are fitted. As shown in FIG. 13(a), first, between the mounting surface 40a and the flat surface 422a of the pressing body 42A, the pin 6 is used to push the strip member 3' into the fitting recess 32a of the strip member 3. The fitting protrusion 32a' is aligned from above. In these strip members 3, the portions that constitute the fitting recesses 32a (hereinafter simply referred to as the fitting recesses 32a) and the fitting protrusions 32a' are stretched by a clearance C (see FIG. 12) during shearing. When aligned, they partially overlap in the vertical direction.

Next, when the pressing body 42A is lowered to the state shown in FIG. 13(b), the fitting convex part 32a' is pushed into the fitting concave part 32a while the fitting concave part 32a and the fitting convex part 32a' are deformed. At this time, the curved sagging surfaces 301a and 302a slide against each other, and the sheared surfaces 301b and 302b extend parallel to each other in the vertical direction, making it easier to push the fitting protrusion 32a' into the fitting recess 32a. There is.

Furthermore, when the pressing body 42A is lowered to the state shown in FIG. 13(c), the fitting protrusion 32a' fits into the fitting recess 32a, and the fitting recess 32a and the fitting protrusion 32a' move in the vertical direction. By being pinched, the engaging surfaces 31a and 31a' are brought into pressure contact with each other. At this time, the convex part 31c of the band-shaped member 3 bites into the sheared surface part 302b of the band-shaped member 3', and the convex part 31c' of the band-shaped member 3' bites into the sheared surface part 301b of the band-shaped member 3, so that a recess is formed in the sheared surface parts 301b, 302b. 31b and 31b' are formed, respectively, thereby restricting the relative movement of the fitting recess 32a and the fitting protrusion 32a' in the thickness direction.

As explained above, the cut ends 31, 31' are formed at the opposing ends of the pair of metal strip members 3, 3', and the cut ends 31, 31' have left and right sides. Fitting portions 35a, 35b, and 35c are formed that are irremovably fitted in the forward and backward directions. Concave portions 31b, 31b' and convex portions 31c, 31c' are respectively formed in opposing engagement surfaces 31a, 31a' in the thickness direction of these fitting portions 35a, 35b, 35c.

According to this, the relative movement of the band members 3, 3' in the left-right direction and the front-back direction is restricted by the respective fitting parts 35a, 35b, 35c, and the band-shaped members 3, 3' are restricted by the recesses 31b, 31b' and the convex parts 31c, 31c'. Since the relative movement of the members 3 and 3' in the thickness direction is restricted, the pair of band-like members 3 and 3' can be connected while their mutual positional displacement is restricted.

In addition, the burrs 301d and 302d are deformed so as to be smooth along the upper and lower surfaces of the strip members 3 and 3' by being compressed by the clamping means 42. In this way, since the strip members 3 and 3' can be connected smoothly, problems with the crimping device 101 and the feeding mechanism 102 can be prevented.

In addition, since each of the engaging surfaces 31a, 31a' is formed by shearing, the characteristics of the opposing engaging surfaces 31a, 31a' are similar, and the engagement surfaces 31a, 31a' that are engaged are similar to each other. Good familiarity.

Further, since the protrusions 31c, 31c' are formed on the engagement surfaces 31a, 31a' by shearing, the protrusions 31c, 31c' can be easily formed.

Further, each of the engaging surfaces 31a, 31a' has a tapered surface portion 36, 36' that tapers downward in the thickness direction, and the engaging surfaces 31a, 31a' are engaged flush with each other. According to this, since the engaging surfaces 31a, 31a' are pressed flush against each other by the tapered surface parts 36, 36', a fitting force can be applied to the fitting parts 35a, 35b, 35c, and the fitting parts 35a , 35b, and 35c can be firmly fitted and connected to each other.

Further, the tapered surface portions 36, 36' are formed with concave portions 31b, 31b' and convex portions 31c, 31c', and the engaging surfaces 31a, 31a are opposed to each other. ', so that in addition to relative movement in the thickness direction of the band members 3, 3', relative movement in the left-right direction and front-back direction is also restricted.

In addition, since the band members 3 and 3' are made of a metal material mainly containing copper, which is easily deformed flexibly, the band members 3 and 3' are twisted and bent in the direction of twisting and bending with respect to the pair of connected band members 3 and 3'. When an external force is applied, the band-like members 3, 3' deform and absorb the external force, so that the fitting parts 35a, 35b, 35c are unlikely to come off. Further, it is easy to form the cut ends 31, 31' on the band-shaped members 3, 3', and it is easy to fit the fitting parts 35a, 35b, 35c.

The band-like member connecting jig 4 also includes a cutting means 41 that forms cutting ends 31 and 31' that are irremovably fitted to the pair of band-like members 3 and 3' in the left-right direction and the front-back direction, respectively; A clamping means 42 is provided that clamps the end portions 31 and 31' in the thickness direction to fit them together. According to this, a recess is formed in the thickness direction of each of the opposing engaging surfaces 31a, 31a' of the cut ends 31, 31' due to the shearing force generated when the pair of band-shaped members 3, 3' are cut by the cutting means 41. 31b, 31b' and convex parts 31c, 31c' are formed facing each other, and when the cut ends 31, 31' are fitted together by the pinching means 42, each fitting part of the cut ends 31, 31' 35a, 35b, and 35c, the relative movement of the pair of band-like members 3, 3' in the horizontal and vertical directions is regulated, and each fitting portion 35a, 35b of each engaging surface 31a, 31a' , 35c, the relative movement of the pair of strip members 3, 3' in the thickness direction is restricted by the fitting of the concave portions 31b, 31b' and the convex portions 31c, 31c'. can be connected to the strip members 3, 3'.

Furthermore, since each fitting portion 35a, 35b, 35c of each engaging surface 31a, 31a' is pinched in the thickness direction by the pinching means 42, each fitting portion 35a, 35b, 35c is crushed. , the pressure contact force between the engaging surfaces 31a and 31a' can be increased.

Moreover, since the cutting means 41 and the clamping means 42 are arranged side by side in the front-rear direction of the strip member connecting jig 4, the cutting means 41 cuts the cut ends 31, 31' on the strip members 3, 3'. After forming, the strip members 3, 3' can be continuously transferred to the clamping means 42 in a short time.

Further, it has a mounting table 40 on which the strip members 3, 3' can be placed, and the mounting table 40 has a mounting table 40 on which the strip members 3, 3' are brought into contact with the cutting means 41 in the left and right direction of the strip members 3, 3'. A pin 5 that restricts movement and a pin 6 that abuts in the left-right direction of the pair of band-shaped members 3, 3' to restrict movement of the cut ends 31, 31' with respect to each other are provided.

According to this, since the belt-like members 3, 3' can be positioned with respect to the cutting means 41 by the pin 5, the rectangular holes 3A and the circular holes 3B alternately continue in a constant pattern along the left-right direction in the belt-like members 3, 3'. ' can be cut by the cutting means 41 at respective corresponding positions. That is, the cut ends 31, 31' always have the same shape including the positions of the rectangular hole 3A and the circular hole 3B. Then, the cut ends 31, 31' are aligned with each other using the pin 6 so that the strip members 3, 3' are continuous in a certain pattern, and the strip members 3, 3' can be connected by the pinching means 42. .

In other words, since it is possible to configure the continuous strip member connection body 1 in the same pattern as the strip member before being broken at the positions of the virtual lines α and β, when the strip member connection body 1 is used, the crimping device It is possible to prevent problems from occurring in the feed mechanism 101 and the feed mechanism 102.

Furthermore, since the pins 5 and 6 are inserted into the rectangular holes 3A and circular holes 3B provided in the strip members 3 and 3', it is necessary to form positioning portions on the strip members 3 and 3'. Therefore, the structure of the strip members 3, 3' can be simplified.

Further, since the pins 5 are arranged on both the left and right sides of the cutting means 41, and the pins 6 are arranged on both the left and right sides of the clamping means 42, when cutting the strip members 3, 3', distortion of the strip members 3, 3' occurs. It is possible to cut accurately by suppressing misalignment, misalignment, and rotation, and when pressing, it is possible to suppress misalignment between the cut ends 31, 31' of the strip members 3, 3' and ensure that they fit together reliably. .

Moreover, since the cutting blade 41A of the cutting means 41 and the pressing body 42A of the clamping means 42 are operated by the same moving means 43, the structure of the strip-shaped member connecting jig 4 can be simplified.

The pressing body 42A is movably attached to the rear of the cutting means 41. Specifically, the pressing body 42A is rotatably supported in the horizontal direction, and has two pressing positions: one in the front side of the cutting means 41 (the state shown in FIG. 12), and the other in the rear side of the cutting means 41. The retracted position (the state shown in FIG. 10) can be changed. When the cutting means 41 forms the cut ends 31, 31' of the strip members 3, 3', the pressing body 42A can be retracted to a retracted position (backward position) where it does not get in the way. This makes it easy to set the strip members 3, 3'.
